4 Claims. 1

This invention relates to new and useful improvements in trucks and moreparticularly to a truck for supporting a chair thereon to com vert thesame into-an invalid chair to facilitate movement of a patient fromplace to place.

An important object of this invention is to provide an invalid chairtruck which may be easily and quickly adjusted to accommodate the legsof chairs of different dimensions.

Another object of this invention is to provide an extensible foot restand which is adjustable independently of the truck and arranged forretracting onto the truck, when not in use for storing and shipping thetruck in a compact form.

A still further object is to provide a device of this character ofsimple and practical construction, which is strong and durable,relatively inexpensive to manufacture and otherwise well adapted for thepurposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a perspective view;

Figure 2 is a top plan view;

Figure 3 is a transverse sectional view taken on the line 3-3 of Figure2;

Figure 4 is a longitudinal sectional view taken on the line 4-4 ofFigure 2, and

Figure 5 is an enlarged perspective view of one of the adjustable slidesfor the sockets of the chair legs.

Referring now to the drawings in detail wherein for the purpose ofillustration I have disclosed a preferred embodiment of the inventionthe numeral 5 designates the truck frame generally which is composed ofa pair of side frame members 6 connected to each other in spacedrelation for lateral adjustment relative to each other by an uppertransverse connecting bar 1 and a pair of lower transverse connectingbars 8. Each of the connecting bars are provided with slots 53 extendinglongitudinally of the bar adjacent each end thereof and in which bolts[0 carried by the frame members 6 are received for securing the framemembers in a laterally adjusted position.

The upper surface of each frame member 6 is: formed with alongitudinally extending dovetail groove H and in which front and reardove-- tail slides l2 and I3 are slidably received. Each slide isprovided with an upwardly extending;

socket M- for receiving the leg [5 of a chair [6 to support the chair onthe frame. Turnbuckles ll are secured at the lower ends of the framemembers 6 and are provided with hooks [8- at their upper end forengaging a rung I9 of the chair to thus securely sold the chair inposition on the frame of the truck.

Swivelly mounted rollers or caster wheels 20- are suitably secured tothe underside of each frame member 6 adjacent the front and rear endsthereof and by means of which the truck with the chair supported thereonmay be easily moved over a floor or other surface.

A foot rest designated generally at 2| includes a pair of spacedparallel side rails 22 which are slidably mounted under the uppertransverse connector 1 and upon the lower transverse-connector 8 tosupport the side rails in the plane of the side frame members 6. A crossbar 23 connects the rear ends of the side rails 22 and is provided witha slot 24 extending longitudinally of the cross bar adjacent each endthereof for receiving a bolt and nut 25 extending downwardly from therails 22 to adjustably secure the rails in spaced parallel relation withrespect to each other inwardly of the inner edges of the frame member 6.A foot board 26 is also adjustably secured at the front end of the rails22 by means of slots 21 extending longitudinally of the foot boardadjacent each end thereof and in which bolts and nuts 28 carried at thefront ends of the rails 22 are adjustably received. The upper surface ofthe foot board 26 is inclined as shown more clearly in Figure 4 to morecomfortably support the feet of a person occupying the chair IS.

The foot rest 2| may be bodily adjusted into a forwardly projectedposition as shown by the dotted lines in Figure 2 merely by sliding thefoot rest forwardly, or may be secured in a retracted position as shownby the full lines in Figure 2 by sliding the same rearwardly.

The side frame members 6 may be adjusted toward or away from each otherby means of the bolts and nuts carried in the slots 9 of the connectorbars l and 8 in accordance with the width of the chair and the socketsI4 may be adjusted forwardly or rearwardly in accordance with thespacing of the front and rear legs of the chair from each other so thatchairs of different dimensions may be secured on the truck.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of theconstruction, operation and advantages of the device will be quiteapparent to those skilled in this art. A more detailed description isaccordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A chair truck comprising a wheeled frame, said frame including a pairof transversely adjustable longitudinal frame members havinglongitudinal grooves in their upper surfaces and cross frame membersconnecting the longitudinal frame members to each other for adjustmentof the latter toward and away from each other, a plurality oflongitudinally adjustable slides recessed in each of said grooves andslidably adjustable longitudinally therein, and chair leg receivingsockets carried by said slides.

2. A chair truck comprising a wheeled frame including a pair of spacedparallel frame members having longitudinal grooves in their uppersurfaces, cross bars adjustably connecting the frame members to eachother, and front and rear slides recessed in each of the grooves of theframe members and each slide adapted to support a leg of a chair placedon said truck.

3. A chair truck comprising a. wheeled frame including a pair of spacedparallel frame members having longitudinal grooves in their uppersurfaces, cross bars adjustably connecting the frame members to eachother, and front and rear slides recessed in each of the grooves of theframe members and each slide adapted to support a leg of a chair placedon said truck, said slides being independently movable forwardly andrearwardly in the respective grooves.

4. A chair truck comprising a wheeled frame including a pair of spacedparallel frame members having longitudinal grooves in their uppersurfaces, cross bars adjustably connecting the frame members to eachother, means carried by the frame for securing a chair thereon, andfront and rear slides recessed in each of the grooves of the framemembers and each slide adapted to support a leg of the chair.
